. To all whom it may concern:

, Be it known that 1, JOHN HAnnrcAN, a citizen of the United States, anda resident of the city and State of New York, have invented certainImprovements in Lifting Devices, of which the following'is aspecification.

' This invention relates to certain improvements in lifting devices, andmore particularly in that class or type of such devices which areespecially designed and adapted for use in connection with wheeledvehicles for lifting heavy loads, and the object of the invention is toprovide a device of this general character of a simple and comparativelyinexpensive nature, and of a strong and compact construction, capable ofquick and convenient application in position for use without requiringany particular or especial skill on the part of the operator, and ofsuch a nature as to permit of being operated from the movement of thevehicle to which it is applied for use, in order to dispense in greatpart with the manual labor and exertion ordinarily required for liftingheavy loads; The invention consists in certain novel features of theconstruction, and combinations and arrangements of the several parts ofthe improved lifting device, whereby certain important advantages areattained, and

Y the device is rendered simpler, less expensive, and otherwise betteradapted and more convenient for use, all as will be'hereinafter fullyset forth. I

The novel features ofthe invention will be carefully defined in theclaims.

In order that my invention may be the better understood, 1 will nowproceed to describe the same with reference to the accompanyingdrawings, 'wherein-' Figure 1 is a view in side elevation of a portionof a vehicle showing a lifting device embodyingmy invention appliedthereto; Fig. 2is a view similar to Fig. 1 showing the-parts operated tolift a loaded receptacle and in such position as to permit thereceptacle to beemptied within the vehicle; Fig. 3is a view inperspective with certain parts of the improved lifting device as hereindisclosed omitted; and Fig. 4 is a detail fragmentary view showingthedevice, in applied position, the wheel to which it is attachedbeingshown in section.

As shown in'the drawings, 1 denotes the body of a cartsupported by thewheel 2,

said cart being herein shown as of a type generally employed in variousmunicipalities v self to the particular style-of vehicle with which thelifting device embodying my invention may be employed.

As hereln shown, the improved lifting device is provided withan'elongated lever member-'3, which may be formed from metal or othermaterial possessing the requisite strength anddurability, and adjacentto one of its ends I have shown said lever member provided withreversely directed curved or angular wheel engaging jaws or members 4,4, spaced apart one from the other in the direction of the length ofsaid lever member, and adapted, when the latter is turned or adjusted ata slight angle to one of the spokes of the wheel to which the improvedlifting device is to be applied for use, to be readily engaged with ordisengaged from such spoke, the angular or overhanging formation of saidaws 4, 4 being,

however," such that when the lever member is m ove d into line with thespoke to which it is applied, said oppositely arranged jaws 4, 4, a'reclampingly engaged over the opposite sides of the spoke in such a manneras to lock the lever member securely thereto, so that said lever memberwill be carried upward say, from the lowered'or horizontal positionshown in Fig. 1 to the raised or vertical position shown in Fig. 2during the turning movement of the vehicle wheel. The length of thelever member, as herein shown, is such that when appliedto the wheel asindicated in Figs. 1 and 2, its outer end portion, opposite to thatwhereat the jaws or wheel engaging members 4, 4 are located, extendsoutwardly beyond the wheel rim in such a manner as to affordsubstantially a continuation or extension of the spoke, and in theembodiment of my invention herein shown, I provide this extended levermember is clampingly secured to a spoke of the wheel by engagement ofits jaws 4, 4, therewith, a load may be quickly and conveniently raisedinto: position to be" dumped into, the vehicle by simple turningmovement of the vehicle, wheel, ensuant upon forward movement of thevehicle itself, without any material physical exertion upon the part ofthe operator.

To further assure an effective engagement of the lever member 3 with thewheel 2, I provide intermediate the length of such lever a laterallydirected jaw or member 5, extending in the same general direction as thejaws or members 4:, 4*, such member 5 being adapted to bridge orstraddle and contact at the outer side of the felly G of the wheel, itbeing understood for conven ience of description that in referring tothe felly the tire thereon is included.

As herein shown, the lifting device constructed according to myinvention is par ticularly adapted to relieve collectors of refuse andthe like from the exertion of the initial or straight lift required whenthe re ceptacles containing such refuse, particularly ashes or the like,are first elevated to be emptied within the body of the vehicle or cart,and as herein set forth the load receiving or supporting means at theouter end of the lever member 3 for engagment with such receptaclesincludes a lifting member or bar 7 pivotally or swingingly coupled withthe outer end portion of the lever member 3 by means of a linkconnection 26, as clearly shown in Fig. l, the lower end portion of suchbar 7 being provided with the hook member 8 adapted to engage the bottomflange 9 of the receptacle 10; but to afford secure engagement of saidhook member and the bottom of the receptacle in case the lat ter may notbe provided with a bottom flange, I have herein shown the free end edgeof the hook member 8 serrated or notched, as at 11, whereby the bottomof a receptacle may be engaged by such hook member 8 without thepossibility of the same becoming detached therefrom during the liftingoperation, as is believed to be obvious.

By this construction, the direct strain of the lift will be upon thebase of the receptacle 10, which arrangement I have found in practice tobe of particular advantage. In order to maintain the receptacle 10 in engagement with the hook member 8 and to assure secure engagement withsuch receptacles as may be provided with handles, 1 provide adjacent theupper end of the bar 7 the elongated ear or auxiliary hook member 12extended in the same general direction as the bar 7, and positioned in aplane parallel therewith, which car or auxiliary hook member is adaptedto be readily and conveniently passed through one of the looped handlesor hand grasps 14 usually provided upon the receptacle or can 10,

herein shown as of the style or type gener ally employed in communitieswhere regular collections of refuse are made. In the various styles ortypes of such receptacles or cans, I havefound that the distances between the bottoms of such cans and the to the hook member 8 a distanceslightly less than the least known distance between the base of areceptacle or can and its looped handles or hand grasps, and have shownthe ear or auxiliary hook member 12 terminating at a point relative tothe hook member 8 a r distance in excess of the greatest known distancebetween the base of a receptacle or can and the looped handles or handgrasps ther of, the ear or auxiliary hook member being thus suitablypositioned and made of a length suthcient to enable it to be engagedwith the handle of the receptacle at whatever distance the same may bedistant from the bottom of said receptacle.

In the employment of my device, it is only necessary that the levermember 3 be en gaged in a manner as has been hereinbefore set forth witha spoke 5 most convenient to the receptacle or can to be lifted, to passthe car 12 through one of the looped handles or hand grasps 1a; and tocause the hook member S to be engaged with the base of the receptacle orcan 10 which may be accomplished by slightly tilting the receptacle,after which the draft animal is caused to advance sufficiently to bringthe lever member 3 is a vertical position, the pivotal or swingingengagement of the lever member 3 with said lifting member or bar 7permitting the latter, together with the can or receptacle engaged withthe members 8 and 12, to be readily and conveniently turned in suchdirection by the operator or collector as will cause the upper portionof the receptacle or can 10 to span or bridge the space between thewheel 2 and the top or coping 16 of the cart or vehicle; and when thecan or receptacle is in this position, it is apparent that the operatoror collector, instead of being required to exert a direct lift, ispermitted the advantage of a short leverage motion to empty thereceptacle or can of its contents.

In order to obtain the best results, find it desirable that thesupporting wheel 2 with which my invention is employed should 7e lockedagainst rotation when the lever member 3 assumes a vertical position,and as herein disclosed I accomplish this result through the medium of aflexible member 18 possessing the necessary strength, and herein shownas a link chain, such connec tion having one end anchored as at 19 tothe lever 3 at a point adjacent the member or aw 5 and having itsopposite end terminating in a hook member 20 adapted for engagement withthe tail 21 of the cart, the length of such connection 18 being such asto terminate or lock the rotary movement of the wheel 2, when the levermember 3 has assumed an upright position. In order 1 ,iemoaezpossibilityof injury to such connection or member 18. As herein set fortlr, thedevice 22 terminates at each end in the hook like members 28, 23 inengagement with certainof the links 24, of the chain ina manner.

which is particularly set-forth in Fig. 4.

While I do not wish to limit myself to any particular arrangement foreffecting the connection between the bar 7 and the lever 3, I prefer toemploy the construction shown in the drawings, wherein acl' evi's- 25 ispivotally engaged with the outer end portlonof such lever 3, said clevisbeing connected with the upper end of the bar 7 by a link 26 passingtherethrough and through an eye projecting from said arm 7.

From the foregoing description of my improvements, it is thought to beobvious that a lifting device constructed in accordance with myinvention is of a simple and comparatively inexpensive nature, and isparticularly well adapted for use by reason of the material lessening oflabor required and by the facility with which it may be operated; and itwill also be obvious from the foregoing description that my improvedlifting device is susceptible of some modification without materialdeparture from the principles and spirit of my invention, and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice.
